I don't see how this method increases dr by much. Doing this with AG manipulation is by no means innovative and in my opinion will result in tone-mapped image with out much difference from a pure software HDR engine.

There have been several works on adapting pixel gain according to the pixel output signal. See aptina dual gain pixel and aptinas' paper at IISW11 with column level gain adaptive amplifiers or back to 2003 the work of Kawahito..

The patent system is screwed.Auto pixel gain selection integrated on a detector is 1990s technology. How innovative is this? Take a light field detector, add a dynamic range extension technology that was obvious 2 decades ago. Call it new. Get a legally enforcible monopoly on that combination.
